Extension or group ID for phone app

I was originally told that when I set up my Ring Central account, i could see the caller or group that is being forwarded to my cell phone while I am away from the office. Currently, the desktop application supports extension identification, but the phone app only says EC Audio. Please try to develope that feature into the phone app.

I am refering to the iphone app. When I use the desktop app, I can see the extension that is calling. However, when I am away from the office, and I use the phone app, the caller ID says RC Audio. I tried to have it forwarded to my cell phone, but then the caller ID was my company with no extensions. I really need to know which extension it is coming from when I am on my mobile phone.
